Electron spectroscopy is a common method for analyzing surface components of materials.The root surface near the fracture source and the

For the set optimization objective, that is, the minimum peak peak te optimization of transmission error, it is not known

In the development of planetary gear drive, it is found that there is obvious noise in the bench test of

The fracture specimens were cut at the gear break and cleaned several times, then the fracture morphology was analyzed.The micro-morphology

The maximum dynamic meshing force and the dynamic load coefficient of the loaded gear are analyzed respectively. They can provide

1) Decoding According to the encoding mode, the chromosome bit string is decoded to obtain the shape modification quantity is,

① Gene coding of modification parameters Four modification parameters of driving gear are defined as tooth height deflection (is δ),

Rockwell hardness tests were carried out on the surface and center of the intermediate shaft sun wheel at different points.

(1) Comparison between simulation and experiment Figure 1 compares the acceleration simulation and experimental results of pinion end with obvious

First, the differences of gear dynamic characteristics with different friction models are discussed.Figures 1 and 2 show the time and

In order to study the comprehensive influence of meshing force and friction force on tooth surface, a simplified dynamic model

Cut and process the inspection gear along the axial direction and about 1/4 diameter into U-type impact test specimen, and
